T alt 'whom it may concern.'

Be it known that I, Lnvl KNor'r, a citizen of the United States, residing at Altoona,

` in the county of Blair and State of Pennsyl- .door and its frame when the door is closed.

The principal object of the invention is Ito provide a'l metallic weather strip for the above purpose which iscapable of'with- 'Standing-the severe usage to which c ar doors zare' subjected, and the servieeability -of which is limited only bythe lperiod of usel of construction, lcombination and arrange-` ment of parts hereinafter fullyv described fulness of .the car itself.

A still further and more specific yobject of the invention resides in the :provision .of 'a weather strip which -is especially designed `for `use upon t-he side or vertical edges of the door and its frame 'and which consists of complementary metallic strips -havingi Ico-engaging portions, the strip secured to .the :frame having an unat-tached yieldableA .joint portion -to effect ya close' frictional con-` tact between the complementary strips when .the door is closed whereby the entrance ofv water or air between t-he door and its frameI is effect-ually prevented. l

With the above and other objects in view, the invention consists of the novel features and claimed, and illustrated in the-accompanying drawings, in whichthe Adjoor frame and door of a lic Weather strip; Fig. 2 is a similar view through vo ne side ofthe door and its frame showing the door partly open; and Figs. 3 and '4 are detail fragmentary perspective views of. the metallic st-rips.-

Referring in detail lto the drawing 5 designatos the vertical angle bars of the metal' door frame whichl are mounted in the side ofthe car bodyV in any approved manner. Upon these `bars the door 6 is hingedly mounted at one edge for swinging movement into and out of the fra-me. lTo the Fivure 1 is a horizontal section throughj car .showing the same provided' with-my improved metafl-iv tudinal edges, the other edge portions of said strips j projectingl inwardly from the 'frame'bars and being d1sposed at an acute angle t0/the body of the'strlp 4as indicated atl). The extreme :free edge portion of the vstrip is inwardly disposed from the frame bar at right angles to the portion 9 of said strip as indicated at 10. The metallic strip is thusbent'or formed by rolling the same, and the v'free edge portion thereof has a certain amount of inherent resiliency or spring action, the angular-ly disposed `portion 9 thereof tending to hold the edge of the strip in spaced relation to the frame bar 5.

A complementary metallic strip 11 is rig- -idly secured adjacent one of its longitudinal edgesto each vertical edge of the door G upon its outer face-as indicated atlQ.` These strips are vbent at a point `substantially intermediate of their edgs to dispose the same outwardly at an angle to the face of t-he door as indicated at 13, and the unattached rlongitudinal edges of said strips are -anged as indicated at 111-, the resiliency of the metal closely holding the edges of said flanges against the face of the door.

W-'hen the door 6 is forced into the frame -to its closed position, the portions 13 there- `'of'engage with the angularly disposed edge '.portions 9 of the strips 7. It will be Aobserved from reference to Fig. 2 that the strip 11 on the hinged edge of the dooris Vfirst brought into engagement with the strip on the door frame at the corner indicated at 15 which is formed by the provision of the flange 14- on the edge of said strip. This corner of the metallic strip 1.1 engages the portion 9 of the strip 7 and forces the same out-Wardly toward the frame bar 5. Owing` to the resiliency of the free augularly disposed portion 9 of the strip7 hereinbefore referred to, it will be obvious that the tendency of the strip to assume its normal condition will cause the opposed faces of the portions 9 and 10 and 13, 14 of the respec- Q 7. n 1,040,355v
